The Carina Nebula (also known as the Eta Carina Nebula, or NGC 3372) is a large bright nebula that surrounds several open clusters of stars.
Here is this 6X4 degrees widefield image - we can see the huge size of it.
The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth.
It is located in the constellation of Carina.
The nebula is one of the largest diffuse nebulae in our skies.
The Keyhole nebula is seen just right of the center (very small).
It is four times as large and even brighter than the famous Orion Nebula.
